Description

Technical Field

[0001] This application relates to the field of oral imaging equipment technology, and more specifically, to a protective shell structure, an intraoral imaging plate pouch structure, and an intraoral positioning system. Background Technology

[0002] Dental imaging components include an external X-ray emitting device and an intraoral imaging device. The imaging device includes an intraoral imaging plate, which can be film or a phosphorescent plate. When using film, X-rays cause a chemical reaction in the photosensitive emulsion (silver halide crystals) on the film, forming a latent image. Subsequent development and fixing processes reduce the silver halide to metallic silver particles, ultimately converting it into a visible image. Film is disposable and must be sealed in a pouch. When using a phosphorescent plate, X-rays irradiate the plate, and the phosphorescent material absorbs the X-ray energy. A specific scanner or reading device, using a laser or other light source, excites the phosphorescent material, causing it to release visible light. This visible light is received by a detector and converted into digital signals, ultimately displayed on a computer. The phosphorescent plate is placed in a pouch and can be reused. The X-ray emitting device emits X-rays, and the intraoral imaging plate needs to be housed in a pouch, forming a pouch structure. After the pouch structure is placed inside the mouth, the imaging plate inside the pouch receives X-rays for subsequent development. In existing technologies, a positioning device is added to align and position the dental X-ray machine. However, the positioning device is placed directly in the oral cavity, which can cause contamination and is very troublesome and inconvenient for doctors to use. Utility Model Content

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] As attached Figure 1 To be continued Figure 8As shown, a protective shell structure includes a shell 3 and a magnet 4. The shell 3 is used to accommodate the magnet 4. The shell 3 is provided with a receiving cavity 31 with an opening facing one end. The magnet 4 is disposed in the receiving cavity 31. A connecting part 34 is provided on one side of the shell 3. The connecting part 34 is adapted to be installed on an intraoral imaging plate bag structure.

[0039] The housing is used to house the magnet 4, which can seal and protect the magnet, prevent the magnet from directly contacting the patient's mouth, ensure safety and hygiene, prevent the magnet from being contaminated, and facilitate the use of dentists.

[0040] Example 1

[0041] As attached Figure 1 As shown, optionally, the housing 3 is adapted to be installed inside the intraoral imaging plate pouch structure, and the connecting part 34 is adapted to be installed on the inner side of the pouch of the intraoral imaging plate pouch structure or on the side of the imaging plate.

[0042] The housing 3 is placed directly inside the first sleeve 1 of the intraoral imaging plate sleeve structure. The first sleeve 1 can simultaneously seal and protect the housing 3 and the magnet 4, preventing the magnet 4 from directly contacting the patient's oral cavity, preventing contamination, and preventing the magnet 4 from malfunctioning. Furthermore, the magnet 4 is fixed inside the housing 3, which can be reused, avoiding waste and saving costs. Simultaneously, the outer side of the connecting part 34 abuts against the inner wall of the first sleeve 1, preventing the housing 3 from shaking or shifting within the first sleeve 1, thus fixing the magnet 4 in place. This prevents errors in the imaging angle and position caused by the magnet 4's displacement, reduces the need for repeated imaging, shortens treatment time, and minimizes the increased radiation dose to the patient caused by multiple imaging sessions.

[0043] Furthermore, the bag is the first bag 1, and the image plate is the photosensitive element 2. In this embodiment, the housing 3 is placed inside the first bag 1 and abuts or connects with the inner side of the bag or the side of the image plate.

[0044] Optionally, the connecting portion 34 is configured as a flange extending outward from the opening of the receiving cavity 31, and the outer surface of the connecting portion 34 is adapted to abut against the inner wall of the bag. The housing 3 with the flange ensures that the outer surface of the connecting portion 34 abuts against the inner wall of the first bag 1, preventing the housing 3 from shaking or shifting within the first bag 1, thus fixing the magnet 4 and avoiding errors in the shooting angle and position caused by the displacement of the magnet 4, reducing repeated shooting, shortening treatment time, and reducing the increase in radiation dose to the patient caused by multiple shootings.

[0045] Optionally, the outer surface of the connecting part 34 has a protrusion, which allows the dentist to accurately locate and place the corresponding tooth in the patient's mouth by feeling the position of the protrusion with their fingers when pinching the intraoral imaging plate pocket structure, thus improving the blind operation effect.

[0046] Optionally, the housing 3 is a one-piece plate structure. The recessed cavity is the receiving cavity 31, and the corresponding protrusion is the convex shell constituting the receiving cavity 31. The flange 34 is the outer edge plate surface. The structure is simple, low in cost, and easy to manufacture and install.

[0047] Example 2

[0048] As attached Figure 4 To be continued Figure 5 As shown, optionally, the receiving cavity 31 is provided with a first buckle 32 and / or a limiting rib 33 for fixing the magnet 4. After the housing 3 is fixed to the first sleeve 1, the receiving cavity 31 forms a sealed space, which can protect the magnet 4, prevent the magnet 4 from directly contacting the patient's oral cavity, prevent contamination, and prevent the magnet 4 from malfunctioning. Moreover, the magnet 4 is fixed in the housing 3, which facilitates the fixing of the magnet 4 and the first sleeve 1, avoids errors in the shooting angle and position caused by the displacement of the magnet 4, reduces repeated shooting, shortens treatment time, and reduces the increase in radiation dose to the patient caused by repeated shooting. At the same time, the protective shell can be used and discarded, and a new protective shell can be installed for the next use, which is convenient for dentists.

[0049] Optionally, the receiving cavity 31 is provided with at least two first latches 32 and at least two limiting ribs 33. The first latches 32 are symmetrically arranged on the inner sidewall of the receiving cavity 31, and the limiting ribs 33 are symmetrically arranged on the inner sidewall of the receiving cavity 31. The symmetrically arranged first latches 32 and limiting ribs 33 can simultaneously limit the magnet 4 and fix the magnet 4 in the housing 3, avoiding errors in the shooting angle and position caused by the displacement of the magnet 4, reducing repeated shooting, shortening treatment time, and reducing the increase in radiation dose to the patient caused by multiple shootings.

[0050] Example 3

[0051] As attached Figure 6As shown, optionally, at least three limiting ribs 33 are provided inside the receiving cavity 31, and the limiting ribs 33 are arranged in an array on the inner sidewall of the receiving cavity 31. The arrayed limiting ribs 33 can limit the magnet 4 around the magnet 4 and fix the magnet 4 inside the housing 3, avoiding errors in the shooting angle and position caused by the displacement of the magnet 4, reducing repeated shooting, shortening treatment time, and reducing the increase in radiation dose to the patient caused by multiple shootings.

[0052] Example 4

[0053] As attached Figure 7 As shown, optionally, the receiving cavity 31 is provided with at least one first buckle 32 and at least two limiting ribs 33. The first buckle 32 is disposed on the inner sidewall of the receiving cavity 31, and the limiting ribs 33 are symmetrically disposed on the bottom wall of the receiving cavity 31. The symmetrically disposed limiting ribs 33 can limit one end of the magnet 4, while the first buckle 32 can limit the other end of the magnet 4, fixing the magnet 4 in the housing 3. This avoids errors in the shooting angle and position caused by the displacement of the magnet 4, reduces repeated shooting, shortens treatment time, and reduces the increase in radiation dose to the patient caused by multiple shootings.

[0054] Optionally, the limiting rib 33 is inclined toward the magnet 4. This allows the inclined limiting rib 33 to limit one end of the magnet 4 when it is inserted into the receiving cavity 31, after which the other end of the magnet 4 can be pressed into the receiving cavity 31. The first buckle 32 then limits the other end of the magnet 4, facilitating assembly and preventing errors in the shooting angle and position due to displacement of the magnet 4.

[0055] Optionally, the connecting portion 34 is configured as a flange extending outward from the opening of the receiving cavity 31, and the housing 3 is connected to the intraoral imaging plate sleeve structure through the flange. When the housing 3 is fixed to the first sleeve 1, the flange fits snugly to the first sleeve 1, so that the receiving cavity 31 forms a sealed space, which can protect the magnet 4, prevent the magnet 4 from directly contacting the inside of the patient's oral cavity, prevent contamination, and prevent the magnet 4 from malfunctioning. Moreover, the magnet 4 is fixed in the housing 3, which facilitates the fixation of the magnet 4 and the first sleeve 1, avoids errors in the shooting angle and position caused by the displacement of the magnet 4, reduces repeated shooting, shortens treatment time, and reduces the increase in radiation dose to the patient caused by multiple shootings.

[0056] Furthermore, 3M adhesive 36 is provided on the flange, and the housing 3 is connected to the first sleeve 1 through the 3M adhesive 36. The 3M adhesive 36 allows for immediate use after removing the outer sticker, making it convenient and durable.

[0057] Furthermore, the housing 3 is disposed outside the first sleeve 1. This facilitates the disassembly and assembly of the magnet 4 when the magnetic force needs to be replaced or adjusted. The magnet 4 can also be adjusted according to different application requirements, providing greater flexibility. At the same time, it eliminates the need to consider the installation position and space when placed inside the first sleeve 1, reducing processing costs. It also facilitates the addition of the magnet to existing intraoral imaging plate sleeve structures, enabling accurate positioning of the intraoral imaging plate sleeve structure 100. This allows for easy adjustment of the relative position between the radiation emitting device 200 and the intraoral imaging plate sleeve structure 100, enabling single-image imaging and avoiding repeated imaging, shortening treatment time, and reducing the increased radiation dose to the patient caused by multiple imaging sessions.

[0058] Example 5

[0059] As attached Figure 8 As shown, optionally, a plurality of limiting ribs 33 are provided within the receiving cavity 31, and the limiting ribs 33 are disposed on the inner sidewall and / or bottom wall of the receiving cavity 31. The limiting ribs 33 can limit the magnet 4 around its perimeter and fix the magnet 4 within the housing 3, avoiding errors in the shooting angle and position caused by the displacement of the magnet 4, reducing repeated shooting, shortening treatment time, and reducing the increase in radiation dose to the patient caused by multiple shootings.

[0060] Optionally, the housing 3 is further provided with a protective cover 5, which is snapped onto the housing 3. The protective cover 5 and the housing 3 are connected by a connecting piece 6, which has a notch 61. The protective cover 5 can be connected to the housing 3, so that the receiving cavity 3 forms a sealed space, which can protect the magnet 4, prevent the magnet 4 from directly contacting the inside of the patient's mouth, prevent contamination, and prevent the magnet 4 from malfunctioning. Moreover, the magnet 4 is fixed in the housing 3, which facilitates the fixation of the magnet 4 and the fixation of the magnet 4 to the first sleeve 1, avoiding errors in the shooting angle and position caused by the displacement of the magnet 4, reducing repeated shooting, shortening treatment time, and reducing the increase in radiation dose to the patient caused by multiple shootings. The notch 61 facilitates the deformation of the protective cover 5 when it is folded 180 degrees and connected.

[0061] Furthermore, the protective cover 5 is provided with a ring of ribs 51, which are adapted to the inner wall of the receiving cavity 3, so that the receiving cavity 3 forms a sealed space, which can prevent saliva from entering the receiving cavity 3.

[0062] Furthermore, the protective cover 5 is snapped together with the housing 3 via the second snap 9. A snap-fit ​​groove is provided at the bottom of the snap position on the housing 3, which makes it easy for the user to open the second snap 9.

[0063] Furthermore, a positioning groove 35 is provided on the end face of the housing 3 or the protective cover 5. This facilitates positioning, allowing the magnet 4 to be positioned at the center of the housing 3, thereby fixing the housing 3 at the center of the first cover 1 and improving positioning accuracy.

[0064] Furthermore, the housing 3 is made of plastic and is transparent. The walls of the housing 3 are relatively thin, so the magnet 4 can be easily squeezed out by slightly pressing the two sides of the limiting rib 33.

[0065] Furthermore, the end face of the limiting rib 33 facing the opening of the receiving cavity 31 is provided with a sliding surface, which facilitates pressing the magnet 4 to fix the magnet 4 between the first buckle 32 and / or the limiting rib 33. The limiting rib 33 and the magnet 4 are interference-fitted, which prevents the magnet 4 from falling off during the pasting process. At the same time, the receiving cavity 31 can be set to correspond to the shape of the magnet 4, or the volume of the receiving cavity 31 can be larger than the volume of the magnet 4, so that the magnet 4 can be pried out using the extra gap after the X-ray is taken.

[0066] Furthermore, the photosensitive element 2 is configured as either film or a phosphorescent plate. When using film, X-rays cause a chemical reaction in the photosensitive emulsion (silver halide crystals) on the film, forming a latent image. Subsequently, through development and fixing processes, the silver halide is reduced to metallic silver particles, ultimately transforming into a visible image. The film is a disposable item and must be sealed in the first bag 1 before use. When using a phosphorescent plate, when X-rays irradiate the phosphorescent plate, the phosphorescent material absorbs the energy of the X-rays. Then, using a specific scanner or reading device, the phosphorescent plate is irradiated with a light source such as a laser. The excited phosphorescent material releases visible light, which is received by a detector and converted into digital signals, ultimately displaying the image on a computer. The phosphorescent plate is placed in the first bag 1 and can be reused.

[0067] Furthermore, when the photosensitive element 2 is configured as a phosphorescent plate, the housing 3 is fixed to one side of the transparent surface of the first sleeve 1. When the photosensitive element 2 is configured as a phosphorescent plate, since the first sleeve 1 has a black surface and a transparent surface, and the phosphorescent plate has a black surface and a photosensitive surface, during installation, the photosensitive surface of the phosphorescent plate is placed into the first sleeve 1 with the black surface facing it. During imaging, the photosensitive surface of the phosphorescent plate needs to face the X-ray emitting device 200, that is, the black surface of the first sleeve 1 faces the X-ray emitting device 200. Therefore, the magnet 4 needs to be placed on one side of the transparent surface of the first sleeve 1, that is, on the side of the black surface of the phosphorescent plate, to prevent the magnet 4 from blocking the photosensitive surface of the phosphorescent plate or affecting the imaging. When the photosensitive element 2 is configured as film, there is no such requirement.

[0068] Furthermore, the housing 3 is fixed to the first sleeve 1 with 3M double-sided tape. Since some dental clinics have limited space and a wide variety of dental equipment, and the intraoral imaging plate sleeve structure 100 itself is small, it would take considerable time to find if placed carelessly. However, the magnet 4 externally mounted on the first sleeve 1 of the intraoral imaging plate sleeve structure 100 has an adsorption function, allowing the intraoral imaging plate sleeve structure 100 to be adsorbed and placed on dental equipment or in a specific location, such as a dental instrument tray, for easy access, reducing search time and preventing contamination from careless placement, thus improving the safety of the intraoral imaging plate sleeve structure 100. After the test is completed, the first bag 1 and the housing 3 are disassembled, and the magnet 4 and the photosensitive element 2 are taken out respectively. The magnet 4 is cleaned and disinfected, and then the magnet 4 is put back into the new housing 3. The photosensitive element 2 is put into the new first bag 1, and the new housing 3 is fixed to the new first bag 1. Then the intraoral imaging plate bag structure 100 can be adsorbed and placed on dental equipment or a specific location for easy access next time.

[0069] This application also provides an intraoral imaging plate pouch structure, which adopts the following technical solution:

[0070] An intraoral imaging plate bag structure is provided for use with a radiation emitting device 200. The intraoral imaging plate bag structure 100 includes a first bag 1, a photosensitive element 2, and a protective shell structure. The photosensitive element 2 is disposed inside the first bag 1 and is used to receive X-rays emitted by the radiation emitting device 200 to form a detection image. A magnet 4 is used in conjunction with the radiation emitting device 200 to position the intraoral imaging plate bag structure 100. A connecting part 34 is adapted to be installed on the side of the first bag 1.

[0071] The intraoral imaging plate sleeve structure 100 is equipped with a magnet 4 for positioning. This allows for effective detection of the position of the intraoral imaging plate sleeve structure 100 when the receiving radiation emitting device 200 approaches it, thus achieving accurate positioning of the intraoral imaging plate sleeve structure 100. This facilitates adjustment of the relative position between the radiation emitting device 200 and the intraoral imaging plate sleeve structure 100. In existing technologies, poor imaging requires re-shooting or multiple shots, which is time-consuming and labor-intensive. This application not only provides rapid detection results but also produces images in a single shot, avoiding repeated shooting, shortening treatment time, and reducing the increased radiation dose to the patient caused by multiple shots. It also avoids the waste of film or phosphorescent plates caused by multiple shots. Furthermore, the housing 3 can seal and protect the magnet 4, preventing direct contact with the patient's oral cavity, ensuring safety and hygiene, and preventing contamination of the magnet 4. Additionally, the housing 3 is disposable; a new housing 3 can be installed for the next use, making it convenient for dentists.

[0072] This application also provides an intraoral positioning system, which adopts the following technical solution:

[0073] An intraoral positioning system includes a radiation emitting device 200 and an intraoral imaging plate purging structure 100. The radiation emitting device 200 has an annular circuit board 7, and the annular circuit board 7 has a position detection unit. The position detection unit includes at least three sets of sensing components 8 for detecting the position of the intraoral imaging plate purging structure 100. The sensing components 8 are spaced apart on the annular circumference of the annular circuit board 7. The intraoral imaging plate sleeve structure 100 is equipped with a magnet 4 for positioning. This allows for effective detection of the position of the intraoral imaging plate sleeve structure 100 when the receiving radiation emitting device 200 approaches it, thus achieving accurate positioning of the intraoral imaging plate sleeve structure 100. This facilitates adjustment of the relative position between the radiation emitting device 200 and the intraoral imaging plate sleeve structure 100. In existing technologies, poor imaging requires re-shooting or multiple shots, which is time-consuming and labor-intensive. This application not only provides rapid detection results but also produces images in a single shot, avoiding repeated shooting, shortening treatment time, and reducing the increased radiation dose to the patient caused by multiple shots. Furthermore, the housing 3 can seal and protect the magnet 4, preventing direct contact with the patient's oral cavity, ensuring safety and hygiene, and preventing contamination of the magnet 4. Additionally, the housing 3 is disposable; a new housing 3 can be installed for the next use, making it convenient for dentists.

[0074] Reference Appendix Figure 4 To be continued Figure 5 Optionally, each of the sensing components 8 includes a mounting plate 81 and six detection sensors 82. The detection sensors 82 are configured as Hall sensors, and the position detection unit senses the position of the magnet 4 through the Hall effect of the Hall sensor, thereby achieving the positioning of the intraoral imaging plate pouch structure 100. In the prior art, poorly captured images require re-shooting or multiple shots, which is time-consuming and labor-intensive. This application not only provides rapid detection results but also allows for simultaneous image capture, avoiding repeated shooting, shortening treatment time, and reducing the increased radiation dose to the patient caused by multiple shots.

[0075] Furthermore, the magnet 4 is positioned at the center of the intraoral imaging plate purging structure 100 to improve positioning accuracy. The position detection unit detects the position of the magnet 4 from multiple directions using multiple sensing components 8 evenly distributed around the circumference. When the ray emitting device 200 approaches the magnet 4, its electromotive force changes. The measured magnetic field strength varies with distance, resulting in a change in the output value. The ray emitting device 200 acquires and processes data from the Hall sensor in real time to generate corresponding position information, which is then sent to a display via a communication unit for timely adjustment of the position of the ray emitting device 200. The intraoral imaging plate purging structure 100 is connected to a computer client via a USB port, facilitating the display of captured detection images on the computer client.

[0076] Furthermore, the mounting plate 81 is vertically fixed to the annular circuit board 7, and the detection sensors 82 are grouped together in a predetermined number on the mounting plate 81 and the annular circuit board 7. The detection sensors 82 of each sensing component 8 are distributed in six coordinate directions of a three-dimensional coordinate system. The three-dimensional coordinate system refers to the three-dimensional XYZ coordinate system established with the circumference center of the annular circuit board 7 as the origin, the axial direction of the annular circuit board 7 as the Y-axis, the horizontal direction perpendicular to the Y-axis as the X-axis, and the vertical diameter direction perpendicular to the Y-axis as the Z-axis. The six coordinate directions of this three-dimensional space correspond to the extension directions of the X-axis, Y-axis, and Z-axis.

[0077] Furthermore, the number of sensing components 8 is at least three. When there are three sensing components 8, the included angle formed by adjacent sensing components 8 on the annular circumference of the annular circuit board 7 is 120 degrees. When there are four sensing components 8, the included angle formed by adjacent sensing components 8 on the annular circumference of the annular circuit board 7 is 90 degrees, and so on. The number of sensing components 8 can be adjusted according to actual conditions. In this embodiment, there are three sensing components 8. Each sensing component 8 includes two mounting plates 81. The length direction of one mounting plate 81 is parallel to the X-axis direction of the three-dimensional coordinate system, and the length direction of the other mounting plate 81 is parallel to the Z-axis direction of the three-dimensional coordinate system. The height direction of the mounting plate 81 is perpendicular to the annular circuit board 7. The mounting plate 81 has two mounting surfaces. The detection sensors 82 are mounted in pairs on different mounting surfaces of the mounting plate 81.

[0078] Furthermore, the mounting plate 81 can also be L-shaped, with one part of the L-shaped mounting plate parallel to the X-axis direction of the three-dimensional coordinate system and the other part of the L-shaped mounting plate parallel to the Z-axis direction of the three-dimensional coordinate system, thereby forming the orientation of the two mounting plates 81.

[0079] Furthermore, the aforementioned sensing components 8 are uniformly distributed on the annular circumference of the circular circuit board 7 at intervals of a certain circumferential angle. In specific implementations, the sensing components 8 may not be uniformly distributed at intervals of a certain circumferential angle. For example, the angle between sensing component one and sensing component two on the circumference is 90 degrees, the angle between sensing component two and sensing component three on the circumference is 120 degrees, and the angle between sensing component three and sensing component one on the circumference is 150 degrees. When the sensing components 8 are not uniformly distributed on the annular circumference, the algorithm stored in the data processing unit should be adjusted accordingly.

[0080] Furthermore, each sensing component 8 includes six detection sensors 82, which are respectively mounted on the mounting surface of the mounting plate 81, which is parallel to the X-axis direction of the aforementioned three-dimensional coordinate system, on the mounting surface of the mounting plate 81, which is parallel to the Z-axis direction of the aforementioned three-dimensional coordinate system, and on both sides of the annular circuit board 7. The two sides of the annular circuit board 7 are parallel to the height direction of the mounting plate 81. After the detection sensors 82 are installed, the orientation of each detection sensor 82 corresponds to the coordinate direction in the three-axis coordinate system established with the center of the annular circuit board 7 as the center point. By vertically mounting the mounting plate 81 on the annular circuit board 7 and grouping the detection sensors 82 in a predetermined number on the mounting plate 81 and the annular circuit board 7, the detection sensors 82 are respectively distributed in the coordinate directions of the three-dimensional coordinate system, thereby enabling the sensing component 8 to accurately detect the relative position of the intraoral imaging plate in three-dimensional space.
